Is this list here really necessary? It is obviously biased heavily towards PLT and provides very little information beyond that. In any case, looking at the links in the Scheme FAQ's list would be much more informative, and it would seem a waste to duplicate the entirety of that list.

I think having the list here on csw is better than just referring readers to the FAQ's list, as here entries can be easily added, adapted, expanded etc. In other words, the whole point of a wiki is that is doesn't tend to go out of date as a static HTML page such as the Scheme FAQ. As to the PLT bias, that is easily corrected, no?

I see this as a category listing: What implementations are mentioned on this wiki at all? As for the PLT bias, I do agree. Please feel free to improve the descriptions of the others, or move the PLT description on the implementation page...

I would appreciate the list containing some information about exactly what is required for the final runtime: Nothing, you end up with a native executable; vm or interpreter, with wrappers or without; dynamic libraries; other... This is often a critical choice if you aren't just making something that you'll run on the development machine or which warrant massive software installs on some well known platform on a production system somewhere. The final dependencies, if you will.
In other words a practical description of the implementation in its use instead of theoretical.

At this point, the implementation list is no longer biased, and is much more usable than the FAQ implementation table (which is pretty useless: it has names and URLs only). Suggestion: either list all implementations here, or expand the implementation table in the FAQ.

I needed to put together a cheap summary list of different scheme implementations for a friend. I can't vouch for its quality/accuracy, but with
a little bit of formatting, it might be of use to the right person.
I was originally interested in the last update and reason why a developer
implemented their version of scheme, but I also included the targets and platform iff they were really easy to find.

(pardon the pastebinning of it. I'd feel guilty adding the contents of this to the page. Hopefully someone else will and keep it looking professional. ;) )
